Hadi's government was toppled by Houthi rebels in late 2014 after the rebels stormed south from their stronghold of Saada, and captured large parts of the north.
Since then, more than 10,000 people have been killed in fighting, millions have been forced from their homes and the impoverished country has been pushed to the brink of famine.
With logistical support from the US, the Saudi-UAE alliance has carried out more than 16,000 raids on Houthi-held areas in an attempt to reverse their gains.
The Arab coalition's campaign of air raids has devastated Houthi positions, ammunition depots and bases, but has largely failed to pave the way for the recapture of Sanaa.
